Oh yeah, I crack the window a bit and use the exhaust fan. The gas heater keeps it nice and toasty. In fact I usually wear just a tshirt/sweatpants out there in the winter.As a fellow brother in the Great White North I know that if you heat a space in the winter and try to exhaust the smoke, it get freekin cold really fast. I assume you don't exhaust the smoke in the dead of winter.
Oh yeah... very cool man cave !
Probably the only things I would change would have to do with ventilation. I'd use an even bigger exhaust fan, though the one out there does the job if it's just 1 or 2 guys, and I would put in at least one more window, maybe two even on opposite walls to get some airflow happening. That's just nitpicky stuff though, now that it's getting chilly at nights I'm out there more and more often and still just love my little oasis.Looks like it was built to last! I imagine everything has held up fine since you started, but if you were to do it again would you change anything?
